feat: add pvecontrol vm restore command

[plaffitt]

I didn't configured a shorthand for the --force flag since it would conflict with the shorthand of --follow (-f). I could use -F instead but I think that for a potentially destructive action it is not that bad to always use the long form of that flag.

$ pvecontrol vm restore --help

                         created (defaults to the storage from the backup
